摘要
目的研究数字化与虚拟现实技术在股前外侧皮瓣解剖设计与可视化中的应用。方法①应用“虚拟中国人”男性3号数据集,在薄层断面图像上观察旋股外侧动脉的主要解剖结构,应用Amira 3．1 (TGS)软件对股前外侧皮瓣结构进行计算机三维重建并立体显示。②明胶一氧化铅混悬液灌注的新鲜成人下肢标本1具,行连续螺旋CT扫描,观测旋股外侧动脉分布及彼此间的吻合情况,应用Amira 3．1软件对股前外侧皮瓣结构进行计算机三维重建并立体显示。结果重建的数字化模型可准确反映股前外侧皮瓣的解剖学结构特点。结论重建的图像可以提供正常股前外侧皮瓣三维动态解剖,为临床教学术前皮瓣设计提供了直观的数字化解剖依据；同时可为下一步虚拟手术的设计奠定良好的基础。
Objective To observe the normal structures of arteria circumflexa femoris lateralis （ACFL） and to establish digitized visible models of anterolateral thigh（ALT） flap, which can be used in clinical training and operation design. Methods The cross-sectional images from the VCH Male 3 dataset were reviewed to study ACFL structures on a section-by-section basis. Next, one adult fresh cadaver specimen was perfused with lead oxide-gelatine mixture to be subject to radiographic CT scanning on its lower limbs. Likewise, the cross-sectional images from the CT images were reviewed to study ACFL structures on a section-by-section basis. Three-dimensional computerized reconstructions of ACFL structures and their adjacent structures were conducted from the two sets of data using Amira 3. 1 （TGS） software respectively. Results The three-dimensional reconstructed visible models established by the above two methods perfectly displayed the anatomic relationships of ACFL structures and their adjacent structures. Conclusions Since the digitized images of ACFL structures can offer section by section insights into the ACFL anatomy, their 3D reconstructive models can be applied in clinical training, pre-operative designing and virtual operation procedures.
